Screen sharing in Mountain Lion iMessage

Thank you Ralph,

I should have been more specific.

I only meant that this topic was in regards to screensharing within the iMessages app and not via back to my mac.

Hi,

I thought is was another question rather than a rebuke of the Post about Back to My Mac Screen Sharing.

Sorry about that.

There is another form of Screen Sharing as well.

In System Preferences have Screen Sharing On

In the Finder > Go menu > Go to Server enter VNC:// (and IP address) to contact another Mac.

Your router has to forward the ports required to your Mac for incoming stuff.

You would "call" their Public IP.

So, what is the fix? all my ports are open, and i'm behind a NAT. is there any fix for why i cannot use video or screenshare with iMessage?

My ISP is Charter Communications.

Also, for some reason, I cannot log into this forum using my iPad. It doesn't recognise my public username. Has anyone had this problem?

Ralph, when you say in preferences, "have screen sharing on", would this be the reason why my iMessage program wont allow video chat or screen sharing?

or were you referring to the use of the VNC program. I can get Team Viewer to work on Screen share, even with the screen sharing checkbox unchecked.

I just cannot figure out why video chat no longer works in iMessage, through the AIM account I have. Has Apple disabled this?

I checked my router, all ports are open, but I'm behind a NAT. I know I had no problems using the older iChat program, but for the sake of me, I just cannot figure out what I'm doing wrong.

Hi,

There are two forms of Screen Sharing that you can do without any extra investment (money-wise)

The First uses the Apple Remote Desktop Engine and is set up in System Preferences > Sharing.

In here you can either have Screen Sharing On or Remote Management. (Remote Management is when someone with the Apple Remote Desktop app contacts you)

The Second is the iChat or Messages Screen Sharing.

As you may know from iChat this has an Audio Chat along side.

It works exactly the same in Mountain Lion and the Messages app.

I tend to have the Buddy Lists on view (See Window Menu)

They can be shown individually after unlinking them in the Messages Menu > Preferences > General Section.

Buddy lists will then display the green Video or Audio Only icons:-

1) If the Show items in the View Menu are ticked and

2) if the Video Menu Enable items are ticked (Selecting any will toggle the current setting to it's opposite.)

Make sure that in System Preferences > Security and Privacy > Firewall Options button that IMAgent as well and Messages shows up as an Allowed item.

If you were using a different computer that the earlier OS also check the router is allowing the ports to the IP the current computer has.

Hi,

All your ports are Open where ?

In the Video menu > Connection Doctor > Network tab what sort of NAT does Messages say you router is doing ?

That Said - the iMessage account does not do Video Chats (It invokes FaceTime) or Audio chats at all.

AS Screen Sharing is an Audio Chat with the Screen Sharing VNC connection running along side, the iMessage Account cannot do this either.

To login you need to be using your Apple ID and it's Password and then the software here shows your Posting Alias or Public Username.

HI,

I don't use Skype.

There are two reasons.

1) I spend far too much time with iChat and Messages to learn anything else.

2) I run Little Snitch and Skype wants to make far, far too many connections to none Skype places to make if safe in my opinion.

Little Snitch is an app that can monitor Ports and IP addresses that an app is trying to use when going about it's daily functions.

Last time I tried Skype it wanted to make in excess of 40 connections. Another regular poster here called Defcom (iChat Community mainly) thinks he has experienced it trying to make over 100 connections.

iChat and Messages with an AIM Login makes about 4 connections to AIM (the basic Login, Buddy Pic server, Video Relay if active and the one which tells you which of your Buddies is On line)

Video chat uses just two other ports - port 5678 to contact the SNATMAP Server and th Buddy with the Visible Invite and then the 16402 for the SIP connection and Actual chat (peer-to-peer).

I saw the other post (via email) before Apple deleted it.

Apple IDs used to have issues when the names contained non English character accents such as "ç", "é" or "â" in French for example.

Any chance your ID or password contains such characters ?

The iPad will be running iOS 6.0.1 presumably rather than any version of the OS X.

The issues should checking why that cannot or does not log in to Apple Support Communities.

I am not blocked to one device.

I normally have my G4 Tower logged in using Leopard, a MacBook Pro for 2007 running Snow Leopard and the iMac from 2011 running a version of Mountain Lion.

I have just checked my iPad as well without issue.

I have heard that sometimes there can be issues when logging on from different IP addresses.

Some people never seem to have trouble with this and others do but I have no idea what the trigger is if any.

I would use the iTunes > Store page > Contact Support and follow the trail to Contacting them.

An ID support person may well be able to straighten things out.

I am not sure I can add anything to this discussion via a Chat.

Don't forget to add them to your friend list (AIM/Google Talk/Yahoo). If not, it won't work.
